Para ello:

Implementar la función: decryptMessage( message, freqLang )

Ordena las letras del mensaje encriptado de acuerdo al número de veces que se repiten (de mayor a menor) y compáralo con la tabla de frecuencia de caracteres del lenguaje en que está escrito este mensaje, que para este caso es:

freqLang = "TEOAISRHNUCMDLGWFPYKJBVQX"

(de más frecuente a menos frecuente)

• Tu programa debe imprimir el texto desencriptado en pantalla.
• No uses archivos ni pidas ingresar datos.
• Mantener las mayúsculas y minúsculas del mensaje, así como los saltos de línea.
